Anybody used CYWUSB6934 SPI to antenna (wireless USB) to AVR?
Any experience, observation? Its looks like a very simple and cheap solution to extend AVR SPI to 2.4GHz ISM band.
And Im looking for some assistance to design 2.4GHz antenna on FR-4 PCB (link, pdf).
Im looking for 13MHz quartz for CYWUSB6934 (in EU).
